Glutamin ist das Amid der Glutaminsäure (siehe unten). Zur Supplementierung ist Glutaminsäure zumindest für Deine Zwecke aber nicht geeignet (Vgl. auch >Glutamin Report<)
Noch ein paar Zitate aus der Fachliteratur:
Kreider (Sports Med 1999 Feb; 27 (2): 97-110):
Kreider et al. (Sports Nutrition Review Journal. 1 (1):1-44, 2004.):Zitat:
Glutamine is a common ingredient currently found in many of the weight-gain supplements marketed to athletes. Glutamine is an amino acid which has been suggested to promote muscle growth and decrease exercise-induced immunosuppression.
These contentions are based on animal and human studies that investigated the effect of glutamine on protein synthesis, [23,24] cell volume[25] and glycogen synthesis.[26] Studies also suggest that intense exercise may decrease glutamine levels[27,28] and that this decrease may contribute to exercise-induced immunosuppression in overtrained athletes.[27-29]
In analysis of this literature, it appears that glutamine is an important metabolic nutrient affecting protein synthesis, [23,24] possibly by increasing cell volume and osmotic pressure.[25] Furthermore, glutamine availability directly affects lymphocytic function.[27-29] Branched-chain amino acid (4 to 16g) and/or glutamine supplementation (4 to 12g) has been shown to increase glutamine levels.[22,29]
Consequently, there is some evidence to support glutamine supplementation, in that it may promote muscle growth [23,24] and/or prevent upper respiratory tract infections among athletes.[22,27-29] However, long term studies investigating the effects of glutamine supplementation on protein synthesis, body composition, and the incidence of upper respiratory tract infections during resistance training have yet to be conducted. Consequently, although basic research is promising, additional research is necessary.
...und noch ein schöner Artikel von Jose Antonio: http://www.joseantoniophd.com/website/articles.php?id=1Zitat:
Glutamine is the most plentiful non-essential amino acid in the body and plays a number of important physiological roles 36. Glutamine has been reported to increase cell volume and stimulate protein 94- 96 and glycogen synthesis 97. Theoretically, glutamine supplementation prior to and/or following exercise (e.g., 6-10 g) may help to optimize cell hydration and protein synthesis during training leading to greater gains in muscle mass and strength 36, 98. In support of this hypothesis, a recent study by Colker and associates 99 found that subjects who supplemented their diet with glutamine (5 grams) and BCAA (3 grams) enriched whey protein during training promoted about a 2 pound greater gain in muscle mass and greater gains in strength than ingesting whey protein alone. Although more data is needed, there appears to be a strong scientific rationale and some preliminary evidence to indicate that glutamine may help build muscle.
